Application led November 26, 1915. Serial No. 63,558.
To all whom it may con/cem:
Be it known that I, FRANK CALDWEIL, avcitizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Chio, have invented a certain new and useful Improvement in Fuel- Feeding Systems, of which the following is a specification.
' This invention relates to that classof hy drocarbon combustion devices in which the air and oil are used under pressure to produce the burning or heating medium, and the object of the invention is Ito provide means whereby the hydrocarbons that 1nclude volatile oils or various gases are used in an initial or a primary mixing-tank and with an advancing or accelerating air-pressure back of them and then such accelerated air and oil admixture passed onward into one branch of a Y-jointv whose other branch accommodates an independent air-supply under pressure and then said admiXture and independent air-supply passed onwardinto a coil or worm whose serpentine or 'spiral bore forms a circuito'us passage-way that is adapted to. cause a churning flow andthereby thoroughly mix the said iirst admixture and the said independent air-supply before their final passageinto a distributing d is'- charge-nozzle, the latter having a second 1ndependent air-supply under pressure adapt ed to enter its rear end and pass through the same adjacent theadmixed airandoil passage so that the eXit end or mouth of said discharge-nozzle shall form a final confluentpoint underl suitable control for the peculiar vesicle vapor that now emits beyond for ignition and the combustin purpose desired.
rEhe details of the invention will be more fully described hereinafter and then more particularly pointed out in the claims.
In the accompanying sheet of drawings, Figure 1 is a composit perspective View of my invention in its preferred form and showing an initial air-pressure tank, an initial, aircharged oilsupply-tank, an air and oil initial, reaction or mingling tank under mechanical or agitator control, initial admiXiure-cai'rying pipe and independent air supply, special mixing coil and final 1nde` pendent air-supply and admixture receiving);
and discharge nozzle; Fig. 2, alongitudinal section of the special Y-brancli Joint for receiving the first independent air-supply and admixture after the departure of the latter from the main mixing or mingling tank and delivering the second resultant admiX- ture to the special mixing or mingling coil; Fig. 3, a longitudinal section showing the interior structure of the final-discharge nozzl'e; Fig. 4, a fore end vievsr of the said final- .y discharge nozzle; and Fig. 5,v a transverse" section of Athe said naLdischargenozzle taken on the dotted line w, a', of Fig. l indicates a tank supplied with air un- 3 indicates an oil supply-tank that has an oil-propelling air-pressure pipe 4 thatleads from or taps a conductor-pipe 5 that,` in turn, leads from or taps the said air-tank l.
der pressure from a suitable pump (not shown) through inlet-pipe :2. i
6 indicates an oil exit-pipe leading from'A the top of the oil-tank 3 and having a valvecontrol 7 therein. 4 i
8 indicates a large receptacle' or tank adapted to receive thc oil under pressure .from supply-tank 3 through pipeG and air' under pressure from supplytank 1 through air exit and conductor pipe 9,.both pipes 6 and 9 leading into the top of thc tank 8 at either side the center thereof. An agitator-blade l() is mounted on a shaft 1l in the receptacle 8 for giving the'air and oil their first adinixturing and causing a "due commingliiig of said elements, such being a mechanical one and starting theinov ment of the air and oil through the appara`- tus in what I believe and `find Vto bc the most proper manner. The lower end ol' the shaft 11 is attached to the uppermost edge of the blade l0, anl diametrically bclmv I attach a soCleted-block 12 that engagcsa tapered step 13 which is attachedl centrally in the bottom of the receptacle. The upper end of the shaft extends beyond the top of the receptacle 8 and has miter-car connccengaging and discharging into thc branch 18 of a Y-joint 19 whose straight outer end 19a receives and vdischarges intro the inner 'nozzle 25, as best seen in Figs. 1 and 3.
The spiral,hollow coil 20 serves the special purpose of still further facilitating and augmenting the admixture of the air and oil for the vesicle form of final discharge,
the circuitous or Winding passage of the admixture being especially ellicacious in mingling and churning 1nto a homogeneous 'volume said air and oil that enter therein from the Y-joint 19 and thence depart through a pipe 24 that is surrounded `by a jacket or enveloping and airprotecrtling he exit-end 24 of the pipe 2e is flattened, as bestv seen in Fig. 3, for the purpose of causing the fluid in extremely minute vesicle form to flow or discharge in a thin'. film or flat stream into the space beyond For the desired ignition and combustion, or such utili nation as may be otherwise ontemplated or desired. Airconductor 5 leads from the lower part of the tank 1 to a double ended exit-branch 27 that enters the rear end of the enveloping-nozzle 25 for a supplemental supply or recharge of the initial air-pressure.
rlransversely-arranged set- screws 28, 28 are provided in the flattened mouth 29 of the enveloping' air-jacket or nozzle 25 for the purpose of controlling thc discharge of the Fluid or gases from said nozzle and the exit 24 of the pipe 24. These set-screws are conveniently operated from the side, and the space between their inner ends is that which is regulated for the vesicle or gas discharge. It will be readily seen that the flattening of the exit-end 29 of the air-nozzle 25 ,concentrates the envelop of air around the exitend 24 of the vesicle or gas discharge 24, whereby the said vesicle or gas discharge is completely protected from surrounding deleterious currents of air or the like,`and the result is a perfect delivery vof the fluid or gas to be utilized in its aerated form, and absolutely .perfect combustion ensues that produces the very highest degrees of heat desired at the least'A cost and with the simplest of apparatus or mechanism.
My invention as thus described, is particu# larly intended and adapted for use in con-- nection With the preparation and supply of r heavy oils, in connection with oil burning furnaces and the like. The churning by the paddles in the receptacle S' starts the foam-I4 ing of the oil, and the passage of the `mix- 'turelthrough the fixed helix continues this process While the mixture is being carried forward to'the furnace, the aim being to have the air so incorporated with the fuel that it is Within the, bubbles of the oil, through the oil between the bubbles, and also on the outside of the mixture, thus assuring 1. 1n an apparatus of the character described, 'the combination of an oil receptacle having means therein .for churning the oil to cause the same to foam, and having an outlet, a source of air under pressure connected to said receptacle, an air feed pipe leading from said source and connected to the outlet of said oil receptacle, means for mixing the air and chui-ned fuel from the receptacle, a discharge nozzlein communication with the mixing means, and a second air feed pipeleading from said source of air under pressure and communicating directly with the said nozzle.
, 2. In an apparatus of the character de- Y scribed, the combination of an oil receptacle having means therein for churning the oil to cause the same to foam, and having an outlet, a pipe for feeding air under pressure extending into said receptacleand having its inner end opening adjacent the, lower end thereof, and independent air feeding pipes in communication with the outlet from said receptacle at spaced points.
3. In an apparatus of the character described, the combination of an oil receptacle having means therein for churning the oil to cause the same to foam, and having an outlet, a pipe for feeding air under pressure extending into said receptacle and having its inner end opening adjacent the -lower end thereof, independent air feeding pipes in communication with the outlet from said receptacle at spaced points, .and mixing means-between the spaced points of com munication ofthe said air pipes.
4. In anyV apparatus vof the character described, the combination of means forv churning air and oil, independent pipes for supplying air under pressure, means for mixing. the ehurned air and oil with the air from one of` saidsupply pipes?, and a discharging element having means for delivering the lnxtui'e with the air from the other supply p1 e.
ln an apparatus of the character described, the combination of means for churn.- ing air and oil, independent pipes for supplying air under pressure, means for mixe ing the cliurned air` and oil with the air from one of saidY supply pipes, and a dis- 10 charging element having means for delivering the mixture with the air from the other supply pipe, said disehargingrelement also 1navin means fer controlling the outflow of the mixed fuel with respect to the outflow of air from the last mentiened supply pipe.
